If you do not specify the MERGEBLOCKRATIO option when you create a table, Teradata Database returns the SQL create text for the table as if you had specified the DEFAULT MERGEBLOCKRATIO option.

For example, suppose you create a table named emp_table, but do not specify the MERGEBLOCKRATIO option. Then, you submit a SHOW TABLE request for emp_table.

     SHOW TABLE emp_table;

The SHOW TABLE output is as follows.

     CREATE SET TABLE emp_table, NO FALLBACK, NO BEFORE JOURNAL,
           NO AFTER JOURNAL,CHECKSUM = DEFAULT, DEFAULTMERGEBLOCKRATIO, 
           MAP = TD_MAP1 
           ( emp_no INTEGER )
     PRIMARY INDEX ( emp_no );
